What a cool tank! - Have y'all seen it yet?

[My goodness! Imagine the evaporation - right to your ceiling! And it doesn't mention anything about noise. But a cool concept - a constant cleaning of the glass :p]
 
[Peter, this is a 20g tank, with 8" height. I'm asking tons of questions about it, because I've gotten entranced. :)]
 
[The total cost for everything listed on this page and the Zero Edge lookdown Aquarium Is only $1458.


kinda steep for a 20G

that is pumps and stand included but stilll..........]
 
[Barry, trust me I've been emailing the proud owner of one of those tanks for the past few hours hammering out a number of thoughts on this setup.

Because of its small size, it would be an AMAZING coffeetable setup, if it wasn't for the need for a light right above the darn thing.

I'm trying to figure out a way to prevent siphoning too much, as the return outlet (looks like a plus sign) is submerged about halfway, to provide flow and yet not disturb the surface for viewing. If the return pump failed for some reason, half the tank would drain. A check valve might work, but there has to be a way to keep the water in the top. Almost like a valve that closes when power is off, like they use for CO2 tanks. A UPS would work as well, for short periods of time.]
 
[In a setup like that the return is not much anyways. I guess you could add some small powerheads down low for some added flow. But if you bring the center return line straight up to almost the tank water level. Then you plug the end of the return pipe, then you drill holes around the sides of the return line just below the end where you plugged it. You then take a cap for a several size larger pipe and glue it onto the end of the return pipe. This would force the water coming out of the return line to go staight back down and not give much of any surface motion. Then if the power did go out the tank would only drain to the bottom of the holes in the return line.]
